1) having an upstream inlet
2) and a downstream outlet
3) for the fluid, a pressure-sensitive element
The present invention concerns a regulator valve for regulating fluid pressure and selectably turning flow on or off. The valve has a housing defining a hollow enclosure with inlet and outlet ends. Inside the housing is a seal member and a spool assembly which are movable relative to one another. The spool assembly has a passage through it and is sealed to the housing such that fluid flow from the inlet to the outlet must go through the passage. When the spool assembly engages the seal member the passage is closed and flow through the device is prevented. The spool assembly is exposed to fluid pressure at the outlet end to bias the spool assembly toward the seal member. A spring engages the housing and the spool assembly to bias the spool assembly away from the seal. Balancing of the spring force and fluid pressure controls the separation between the seal member and the passage in the spool assembly, thereby governing the pressure at the outlet of the regulator valve.
